GEORGE R. `wrMArtor EAST wALPoLE, MASSACHUSETTS, AsSIGNoR To CHARLES S. BIRD, DOING BUSINESS UNDER THE NAME AND STYLE or E. W. BIRD & soN, or EAST wALPoLE,

MASSACHUSETTS. y

Be it known that I, GEORGE R. WMAN, a

i citizen ofi-:the Unit'ed States, and a residentof .p Boxes, of which the fo `Ing drawings, in which` East 'Walpole, in the countyl of }N orfolk, State of' Massachusetts, have inventedcer.- tain new and useful Im rovements in Paper v owin is a specification, reference being had to t e accompany- Fi ure 1 is a plan view .of a blank of cardboar cut and scored for my saidimproved box, and showing the reinforcing strips cut away to illustrate the reinforcing cords along the ed es. .Fi 2 is a lanview showing blank folded and secured in Fig..3 is a detail, on an "enlarged scale, showing 1nperspective an inside corner'of one ofv my said boxes, and In sectIon taken on the My invention 1s as applicable to the lid, `or top of the box, as to itsbody or box proper.

Heretofore constructing'folding paper boxes of thin, or comparatively cheap stock, it has tproved difficult toimpart to the corners o the rim therequisitestrength and l .rigidityto withstand the strains incident to ordmary usage. In boxes of this ty e, it is necessary that they should be shippe flat to the user or consumer, inasmuch as there is a' great saving in cost of shipment where such oxes lare not "set up until they reach the factory'where they are to be used. ,InThis class of boxes, pressure upon the ends and sides of the box'or lid is concentrated upon the corners, tending to distort or break the material. L f- To strengthen the box or lid at the corners, numerous means have been devised, all of them of an extraneous, and most of them of an externally a liedcharacter. In U. S. Lettes. Patent o. 873,335, dated Dec. 10, 1907, I disclosed a form of foldin paper box of rectangular shape, constructe vof av single piece of board, whereby its corners were greatly fortified in an economical andefiicient manner by `means integral with the remainder of the box, which means were so combined and disposed as to present the conventionally appearing outside surface of the ordinary, set up box orlid. It has been the experience with my improved box or lid, as'

shown and described in my said vPatent N o. 873,335, that the tendency toftear'fforfjbreak ,spciacation of Letters Patent. Application filed March 18, 1908. Serial No.v 421,817.

Orcingstrip along the si ey asted, glued, or

otherwise secured to-such si e, as is shown in Fig. 1. I attain. this object inthe following' manner.

Figures land 2 show an integral blank'of heavy pa er, card, straw or other paper g boardor t e like, cut and scored in the usual 4Way' for bendingland folding in iinally operative osition, At e triple lines showlng the score portions, and the heavy double lines the' cuts. Such iece of board comprises a bottom piece A wIth side members S, S provided with folded over reinforcing strips s, s', end pieces E, E', having extension flaps e, e', respectively adapted to fold over the extension pieces of the sides and on the inside of the box or lid, and there to be As shown more particularly in Fig. 1, the side members S, S, have at their ends turnedin extensions d, d, d, d/integral therewith and' each of said turned-in extensions having l the .material at the corners is not completely,

glued or other- YWise secured in final position.

integral therewith reinforcing strips d', d',

d', d', which are integral with the reinforcing strips s, s. Such lturned-in extensions are scored so as 'to be adapted to be bent inwardlyv at lright angles to `their reslective sides, as shown more particularly vin 1g. 2. The blank having been thus scored and folded, a reinforcing cord C, is inserted along the inner creases for d by the side S with its extension flaps dll, and the reinforcing stripintegral therewith s, d', and in like manner the cord C is inserted along the inner crease on the opposite side as shown in-Flg. 1,

and then such reinforcing strips s, s', d', are

securely glued or otherwise secured to their respective contiguous side members; then 'the side members S, S', are bent up at right angles with-the bottom A, and then the extension pieces d, with theirextension flaps, are bent in at right an les with the sides, and

have) their lower su aces contacting along thefbottomof the boxV or lid. Then the endpieces EE", are turned up outside of, against, and secureli glued or otherwise aiiixeid to the said turne in extensions d. The extension flaps e, e', respectively of the ends E, E, are then bent over and down on the inside of the box or lid, and are likewise secured to the.

said extensionilaps d', and also, in some cases, to d, byglue or other equivalent means. The box, or lid, as the case may be is thus completedhhaving secured Within itself between the sides and ends along the edge thereof reinforcing cords or strings, which successfully prevent any tear or rugture of the material-at the corners B, B, B1, which experience has revealed are particularly subject to greater strains and tensions than the ordinary card orstraw board is able to Withstand.

rEhe fold connections, as shown in Fig. 3i sufficiently provide, through the four-fold thickness of material, sufficient strength at the ends, and the doublefold of material along the sides successfully withstands any-` bulging strains outwardly from within the box, and by my reinforcing cord or string along the edges of the sides around the corners and artially within the end rims of my box or li provide such strength and rigidity as has not been heretofore attained in boxes of this character.

The form of construction shown and described herein can be applied either to a box or to a lid or cover with equal advantage and with equal stiness and strength. box of considerable depth is desired, the re-I inforcing stri s, in order to save stock, may not .necessa 'y extend on the inside of the box completel to the bottom, but may be made materia ly narrower than the 4 sides without disadvantage.
